In the end, I've ordered a Panasonic Lumix DMC-LX7. Seems to have lots of the things I actually liked and used about a DSLR (low light performance, short depth of field), without the bulk or weight. Weatherproofing would have been nice, but when I thought about it, my little compact (Fuji Finepix F10) survived 8 years of my mistreatment, so hoping to repeat that. And lastly it was cheap - around $340 AUD delivered.

There seems to be a strange lull in compacts at the moment - most of the recommended "premium" compacts available are more than a year old, and prices have come down accordingly. Thanks again to everyone for the recommendations and comments - much appreciated.
